Last month [July] saw the launch of a three-year project led by researchers at the University of California (UC), Santa Cruz, with the aim of developing a fishmeal alternative from an under-utilized microalgae industry co-product.
“The proposed project is a critical part of our larger research program to advance more environmentally sound trout diets by reducing eutrophication emissions, eliminating fishmeal and fish oil and encouraging economically sustainable use of under-utilized resources to directly benefit US aquaculture operations. This grant will help strengthen sustainable environmental stewardship of aquaculture,” Pallab Sarker, Associate Professor of Environmental Studies at UC Santa Cruz, told FeedNavigator.
The project will be funded by a $1m grant from the Agriculture and Food Research Initiative at the USDA National Institute of Food and Agriculture.
“We will use this fund to conduct a series of experiments in the lab, on-farm trials, environmental and economic analysis and extension work,” said Sarker.
Aquafeed: an environmental impact hotspot
Outlining the context to the program, Sarker warned that aquafeed has become an “environmental impact hotspot”.
“The environmental sustainability of aquaculture is of critical concern due to its rapid expansion. There is a need to seek more sustainable aquafeeds to address the environmental impacts associated with aquaculture,” he said.
Sustainable expansion of aquafeeds requires alternatives to fishmeal, said Sarker.
“Diverting forage fisheries to produce fishmeal undermines marine biodiversity. Aquaculture feed is a critical production input as well as a major source of waste in aquaculture systems. Also, poorly digested feed ingredients can increase nutrient emissions (nitrogen and phosphorus) in aquaculture effluents,” he noted.
